I\'m running Xcode 4.3.1 iOS-Simulator which originally only supports iOS 5.1.
I need to test my code with iOS 4.3, so I used Xcode\'s \"Install\" feature to install
In Xcode 6 and above, you can find and delete the simulators from the path /Library/Developer/CoreSimulator/Profiles/Runtimes. Restart Xcode in order to take effect (may not be needed).
